Artocarpus heterophyllus Lam., which is commonly known as jackfruit is a tropical climacteric fruit, belonging to Moraceae family, is native to Western Ghats of India and common in Asia, Africa, and some regions in South America. It is known to be the largest edible fruit in the world. Jackfruit is rich in nutrients including carbohydrates, proteins, vitamins, minerals, and phytochemicals. Both the seeds and the flesh of jackfruit are consumed as curries and boiled forms, while the flesh in fully ripen stage can be eaten directly as a fruit. Several countries have developed different food products such as jam, jellies, marmalades, and ice creams using pureed jackfruit. The several parts of jack tree including fruits, leaves, and barks have been extensively used in traditional medicine due to its anticarcinogenic, antimicrobial, antifungal, anti-inflammatory, wound healing, and hypoglycemic effects. Despite all these benefits, unfortunately, the fruit is underutilized in commercial scale processing in regions where it is grown. The aim of this review is to disseminate the knowledge on nutritional and health benefits of jackfruit, in order to promote utilization of jackfruit for commercial scale food production.

Dye‐sensitized solar cells (DSSCs) have turned a new horizon in energy research due to their widespread exploration over two decades by improving efficiency, cost‐effectiveness, and easy process than inorganic‐based solar cells. The major challenges are metal complexes on designing the cells and sustainability implications for further rapid expansion due to its toxicity. To overcome the problems associated with metal complexes, the dyes are extracted from bionatural sources such as flowers, fruits, barks, petals, roots, leaves, and beans of plants. These organic dyes are being nontoxic, cost‐effective, abundant, environmentally friendly, and easy to extract, which is made them extensively applicable for DSSC. Through this review, readers may get an idea about the effect in the efficiency of the solar cell by applying variable semiconductors, effects of solvents, variable light‐harvesting pigments, types of electrolytes, and modification of counter electrodes by certain polymeric materials or nanomaterials. Furthermore, the effects of methodology, processing temperature, and pH of the medium during synthesis on solar cell parameters, such as the efficiency of DSSC, are critically analyzed which are reported by other researchers.

“…While parts of the ripe jackfruit including the pulpy aril and seeds are a culinary delicacy, the rough, fibrous appendage called ‘rag’ that make up 10-20% of the fruit are either discarded as non-edible fruit waste, or in some cultures, cooked and consumed. There are no known reports of rag’s being used for medicinal purposes, although we have recently reported the use of the Jackfruit rag extract (JFRE) as a photo-sensitizer in solar cells 17 . Since rags make up large parts of the fruit and considering the existing lack of clarity towards their use for human benefit, we set out to explore possible medicinal value of the rag, with specific focus on its potential as an alternative to antibiotics against human pathogenic bacteria.…”

33 34 35 Abbreviations: 36 CFU, colony forming units; DPPH, diphenyl-1-picrylhydrazyl hydrate; FBS, fetal bovine 37 serum; FTIR, Fourier-transform infrared spectroscopy; JFRE, jackfruit rag extract; MBC, 38 minimum bactericidal concentration; MIC, minimum inhibitory concentration; MTT, 3-(4,5, 39 dimethylthiazol2-yl)-2, 5-diphenyltetrazolium bromide; SEM, scanning electron microscope, 40 GC-MS, Gas chromatography mass spectrometry. 41 42 2 Abstract 43The aim of this study was to determine the antibacterial property of extract derived from a part 44 of the Jackfruit called 'rag', that is generally considered as fruit waste. Morpho-physical 45 characterization of the Jackfruit rag extract (JFRE) was performed using gas-chromatography, 46where peaks indicative of furfural; pentanoic acid; and hexadecanoic acid were observed. In 47 vitro biocompatibility of JFRE was performed using the MTT assay, which showed comparable 48 cellular viability between extract-treated and untreated mouse fibroblast cells. Agar well disc 49 diffusion assay exhibited JFRE induced zones of inhibition for a wide variety of laboratory and 50 clinical strains of gram-positive and gram-negative bacteria. Analysis of electron microscope 51 images of bacterial cells suggests that JFRE induces cell death by disintegration of the bacterial 52 cell wall and precipitating intracytoplasmic clumping. The antibacterial activity of the JFREs 53 was further validated in vivo using Shigella dysenteriae infected fly model, where JFRE pre-54 fed flies infected with S. dysenteriae had significantly reduced mortality compared to controls. 55 JFRE demonstrates broad antibacterial property, both in vitro and in vivo, possibly by its 56 activity on bacterial cell wall. This study highlights the importance of exploring alternative 57 sources of antibacterial compounds, especially from plant-derived waste, that could provide 58 economical and effective solutions to current challenges in antimicrobial therapy. 59 60
